Question

(8 points) In physics, Hooke's law states that the length r of a uniform spring is a linear function of the force, y, applied to it. If we write y a +kx, then the coefficient k is called the spring constant. You are asked to determine the spring constant of a ]p spring has an unstretched measured length of 6.1 inches (i.e., r - 6.1 when y 0). You realize that because of experimental error, you want to take more than one measurement. Using forces of 2 pounds, 4 pounds, and 6 pounds applied to the spring, you measure the corresponding lengths to be 7.6 inches, 8.7 inches, and 10.4 inches, respectively. Find the best estimate for the spring constant of this spring. articular spring. This particular
